1 Claim.

The present invention relates to new and useful improvements in washersfor mugs, glasses and other receptacles for use particularly in suchpublic places as taverns, hotels, restaurants, etc., although it will beunderstood, of course, that a device in accordance with the presentinvention may be used in any place for which it may be found adapted anddesirable.

The primary object of the present invention is to provide, in a manneras hereinafter set forth, a washing device of the aforementionedcharacter comprising a novel construction, combination and arrangementof parts, through the medium of which the inside and outside of areceptacle may be rapidly but thoroughly cleansed.

Another very important object of the invention is to provide a washingdevice of the aforementioned character comprising a novel constructionof receptacle opened valve for automatically controlling the dischargeof the washing fluid.

Still another very important object of the invention is to provide, inconjunction with a washing device of the character described, novelmeans for preventing what is commonly known as water hammer when thedevice is in use.

Other objects of the invention are to provide a receptacle washingdevice of the character set forth which will be comparatively simple inconstruction, strong, durable, highly efficient and reliable in use,compact, sanitary. and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in front elevation of a washing device constructed inaccordance with the present invention, a portion of the hammereliminator being broken away in section.

Figure 2 is a view in vertical section through the device, takensubstantially on the line 2-2 of Figure 1.

Figure 3 is a top plan view.

Figure 4 is a detail view in horizontal section, taken substantially onthe line 4-4 of Figure 1.

Figure 5 is an elevational view of the upper end portion of one of thetubes provided for washing the outside of the receptacle.

Referring now to the drawings in detail, it will be seen that theembodiment of the invention which has been illustrated comprises avertical nozzle which is designated generally by the refer- 'encenumeral I, said nozzle including a tube 2 having a slightly enlargedinternally threaded lower end portion 3 providing an external shoulder4. The nozzle I further includes a substantially dome-shaped removabletip 5 threaded on the upper end of the tube 2 and having discharge ports6 therein. The nozzle I still further includes an internal shoulder l inthe lower portion of the tube 2, the purpose of which will be presentlyset forth. The nozzle I is mounted on a water supply pipe 8 through themedium of a T 9 and a nipple II], the latter being threaded into thelower end portion 3 of the tube 2.

Radiating from the lower end portion 3 of the tube 2 are pipes II on theouter ends of which vertical tubes I2 are mounted through the medium ofelbows I3. Removable caps I I are threaded on the upper ends of thetubes I2. In their upper end portions the tubes I2 are provided withdischarge ports I5 which are adapted to spray water inwardly anddownwardly over the bottomand sides of an inverted receptacle on thenozzle I. Mounted on the tubes I2 is a metallic shield I6 for the water,said shield being substantially C- shaped or open at its front toaccommodate the handles of mugs, cups, etc., also the hand of the personusing the device. A horizontal shield in the form of a disk I! rests onthe pipes II and encircles the nozzle I.

The lower portion of the tube 2 of the nozzle I has formed therein aseat I8 with which a valve I9 is engageable. The valve I9 is mounted onthe lower end of a stem 20 which extends slidably through the tip 5 forengagement and actuation by the receptacles to be washed. The referencenumerals 2| and 22 designate upper and lower apertured guides,respectively, for the valve stem 20 in the tube 2, the former beingmounted on said stem for movement therewith, the latter being stationaryand resting on the shoulder 1, said stem 20 being slidably therein. Asleeve 23 is removably mounted on the stem 20 below the guide 2| and aclosing spring 24 is interposed between the sleeve 23 and the lowerguide 22. A pin 25 is provided for limiting upward movement of the upperguide 2| under impulsion by the spring 24. is a comparatively long,heavy cushioning spring 26 which rests on the lower guide 22, the upperend of said cushioning spring being normally spaced from the upper guide2| for allowing sufficient independent initial movement of the stem 20to permit the valve I9 to open.

As illustrated to advantage in Figure 1 of the drawings, a hammereliminator designated gen- Also mounted in the tube 2 of the nozzle Ierally by the reference numeral 21 is connected to the T 9 through themedium of a nipple 2B. The unit 21 includes a cylinder 29 havinginternally threaded end portions for the reception of. closure plugs 30.A drain cock 3| is mounted on the outer end of the unit 21.

Briefly, the operation of the device is lows:

The spring 24 normally maintains the valve ill in closed position, beingassisted by the pressure of the water. The receptacle to be washed isinserted and placed over the nozzle l and sufiicient downward pressureis applied to said receptacle to open the valve 19 against the tensionof the as folspring 24, the bottom of the inverted receptacle engagingthe upper end of the stem 20, as will be understood. After the valve 19opens, the cushioning spring 26 is engaged by the upper guide 2| andyieldingly resists further downward movement of the receptacle, thuspreventing said receptacle from striking the upper end of the nozzle lwith suificient force to be damaged thereby. When the valve l9opens'water is discharged from the ports 6 and I5 over the entire innerand outer surfaces of said receptacle in a manner to thoroughly cleansethe same. It will be noted that the construction and arrangement is suchthat the entire device may be rapidly taken apart or disassembled forcleaning or repairs when desired. Air trapped in the comparatively largecylinder 29 of the unit 2'! cushions the water in a manner to preventhammering when the valve l9 closes during the operation of the device.The cock 3| permits the cylinder 29 to be drained when necessary.

It is believed that the many advantages of 9.

washing apparatus constructed in accordance with the present inventionwill be readily understood, and although a preferred embodiment of theinvention is as illustrated and described, it is to be understood thatchanges in the details of construction and in the combination andarrangement of parts may be resorted to which will fall within the scopeof the invention as claimed.

What is claimed is:

A receptacle washer comprising an upstanding nozzle having ports in theupper end thereof and receivablein a receptacle, a plurality of. pipescommunicating with the lower portion of said nozzle, tubes rising fromsaid pipes in spaced relation to said nozzle and being provided withports in the upper portion thereof, the lower portion of said nozzlebeing adapted to be connected to a source of liquid supply, a valve seatin the lower portion of said nozzle, a stationary valve guide in saidnozzle, adjacent said valve seat, a slidable guide having a dependingsleeve, a valve for contacting with the valve seat and having arodextending upwardly through the stationary guide and said sleeve of theslidable guide and projecting beyond the upper end portion of thenozzle, a coil spring disposed in said nozzle between the stationary andthe slidable guide, a coil spring encircling said valve rod and disposedbetween the stationary guide and the lower portion of said sleeve, meansconnecting said valve rod to said slidable guide, a substantiallyO-shaped shield mounted on the tubes and a horizontal shield encirclingthe lower portion of the nozzle, and resting on said pipes.
